I study the atmosphere and ocean, focusing on geophysical fluid dynamics, climate change, and numerical modelling. On the GFD/climate side, I am interested in how waves, turbulence, and jets are generated and how they will respond to climate change. On the modelling side, I am interested in improving simulations by designing better time-stepping methods and developing stochastic representations of subgrid-scale features.
These are challenging scientific problems with important societal implications. I tackle them using computer simulations (with everything from conceptual toy models to general circulation models) and laboratory experiments.
Some recent highlights from my research group are listed below, with links to published papers.
- Time stepping
- Stochastic modelling
- Climate change
- Quasi-geostrophic theory
- Quasi-geostrophic theory performs well even outside its formal limits.
- I led the development of QUAGMIRE, a quasi-geostrophic numerical model of the rotating annulus.
